Can likely thermal ignition conditions of ignition be characterized?
Considering the use (scenario) to which the building is intended, the natural or artificial environment that hosts it, it is possible to hypothesise whether the product comes in contact with:
- a) a quantity of radiated heat for a given time,
- b) a thermal power of the open flames for a given time,
- c) a thermal power of the incandescence for a given time.
These agents have to be "quantified" in order to decide a process of artefact evaluation consistent with the scenario in which operates.
In each of the indicated cases, even considering the manufactured product victim of the fire, it is necessary to define if the product, for its nature or the position it occupies, can be sensitive to these factors and also ends up in order to contribute to the fire development.
We need to be aware that, during the development of the fire, any organic product participates in the event. In this case a reflection on the possible ways of lighting the building and its reactivity to the phenomenon can be done.
Once the direct or indirect igniting conditions have been identified, it will be necessary to reproduce them with one or more small-scale tests (see IEC series 60695-11-XX previously mentioned).
